As a slight thread drift on aircraft not flown on, shortly after (a couple of months) the present Mrs NC and I got together, Mrs NC who then was responsible for a lot of corporate travel bookings for her employer was asked by her travel agent (no on-line booking in the 1980's) to go on a jolly to London for a couple of days. Said jolly included a Concord experience flight from Heathrow. The present Mrs NC declined as she didn't want to leave me for a couple of days. Mrs NC now regrets that decision.
